A portion of rainfall which moves down to the streams, lakes, channel or river as surface or sub-surface flow results in_____.

  • A.Transpiration
  • B.Hydrologic Cycle
  • C.Evaporation
  • D.Runoff

Answer: D

It results in Runoff.

Runoff is the part of precipitation that, after interception, infiltration and evaporation losses, flows to streams, lakes, channels and rivers, either over the surface (surface runoff) or just below it (interflow or subsurface runoff), together with base flow from groundwater.

Transpiration and evaporation return water to the atmosphere. The hydrologic cycle is the whole circulation of water, not the particular portion that moves to streams.
